DETAILED DESCRIPTION OF THE INVENTION

File download systems and methods are provided. FIG. 1 is a schematic diagram illustrating an embodiment of a file download system. The file download system 1000 comprises a content provider 1100, at least one client 1200, an email box 1300 owned by the client 1200, and at least one file authority owner 1400.
The content provider 1100 comprises a user password table 1110, a user authority table 1120, a user data table 1130, a processing module 1140, an interface 1150, and a file database 1160 comprising at least one file 1161. The content provider 1100 uses the user password table 1110 to authenticate a client upon login. FIG. 2 is a schematic diagram illustrating an embodiment of the data structure of a user password table. As shown in FIG. 2, the data structure of the user password table 1110 comprises a user identification field 1111 and a password field 1112 for respectively storing a login account on the content provider 1100 and a corresponding password. The content provider 1100 uses the user authority table 1120 to determine whether a user has authority to download a specific file. FIG. 3 is a schematic diagram illustrating an embodiment of the data structure of a user authority table. As shown in FIG. 3, the data structure of the user authority table 1120 comprises a user identification field 1111 and a file download authority field 1121 for respectively storing a login account on the content provider 1100 and authority to download a specific file. FIG. 4 is a schematic diagram illustrating an embodiment of the data structure of a user data table. As shown in Fig.4, the data structure of the user data table 1130 comprises a user identification field 1111 and an email address field 1131 for respectively storing a login account on the content provider 1100 and an email address corresponding to the login account. The processing module 1140 performs user authentication according to the user identification 1111 and password 1112 input by a user, download authority determination to determine whether the user has authority to download specific data if the user passes the authentication and wants to download the specific data on the content provider 1100, and file download by directly transmitting the specific data to an email box corresponding to the user. Additionally, the client 1200 can browse and request to download the file 1161 in the file database 1160 via the interface 1150. It is understood that the file authority owner 1400 can be a system administrator of the content provider 1100 or personnel having authority for the file 1161.
FIG. 5 is a flow chart -showing an embodiment of a file download method. In step S501, the client 1200 inputs identification data, such as user identification and a password to log into the content provider 1100. In step S502, the content provider 1100 authenticates the client 1200 according to the identification data inputted before. It is understood that the authentication is performed by checking whether the user identification is set in the user password table 1110, and if so, determining whether the input password conforms to the set password of the user password table 1110. If the authentication fails, proceeding to step S503, an error message is generated. In step S504, it is determined whether the client 1200 wants to apply for an account. If not, the procedure is completed. If so, the content provider 1100 generates an account for the client 1200 automatically, or based on direction of a system administrator. The procedure goes to step S506.
Judge whether the authentication passes in step S502. If so, go to step S506. In step S506, the client 1200 is granted to entry the content provider 1100, and browses the file 1161 in the file database 1160 via the interface 1150. In step S507, it is determined whether the client 1200 wants to download the file 1161. It is understood that, in some embodiments, the client 1200 may generate a download request for the file 1161 by selecting a link (not shown) corresponding to the file 1161 in the interface 1150. If the client 1200 does not want to download the file 1161, the procedure returns to step S506 the client 1200 can use the interface 1150 to browse other files in the file database 1160. If the client 1200 wants to download the file 1161, proceeding to step S508, the content provider 1100 determines whether the client 1200 has authority to download the file 1161 by checking whether the data recorded in the authority field 1121 of the user authority table. 1120 corresponding to the user identification 1111 of the client 1200 is valid in step S509. If so, proceeding to step S510, the content provider 1100 retrieves an email address inputted by the client 1200 from the user data table 1130 according to the user identification of the client 1200, and transmits the file 1161 to the email box 1300 according to the retrieved email address. If not, proceeding to step S510, the content provider 1100 transmits a confirmation letter to the file authority owner 1400 for approving the download of the file 1161. If the confirmation is not approved by the file authority owner 1400, proceeding to step S513, the content provider 1100 transmits a letter of download denied to the email box 1300 inputted by the client 1200. If the confirmation is approved by the file authority owner 1400, proceeding to step S510, the content provider 1100 retrieves an email address of the client 1200 from the user data table 1130 according to the user identification of the client 1200, and transmits the file 1161 to the email box 1300 according to the retrieved email address. It is understood that after the file authority owner 1400 makes a decision to the download confirmation, the file authority owner 1400 transmits a reply, a message or an email message comprising the confirmation result to the content provider 1100, and the content provider 1100 determines the confirmation result accordingly. Therefore, the client 1200 can connect to the email box 1300, and acquire the file 1161 transmitted from the content provider 1100 therefrom. It is understood that a system (not shown) providing the email box 1300 may have a user authentication mechanism. When the client 1200 connects to the email box 1300, identification data must be input to the system for authentication to login the email box 1300 for acquiring the file 1161.
